Link sharing has become a popular activity in software engineering, which enables developers to share knowledge and mitigate potential issues.
The value of link sharing has been commonly addressed in question-and-answer forums like Stack Overflow and tool-based code reviews like GitHub and Gerrit.
Goemz et al. [1]} reported that link sharing is a significant phenomenon on
Stack Overflow, referring readers to software development innovations like libraries and tools.
Ye et al. [2]} generated the structural and dynamic properties of the emergent knowledge network, using shared URLs in Stack Overflow.
With the popularity of GitHub, Hata et al. [3]} found that 9.6 million links exist in source code comments across 25,925 repositories.
Within Gerrit based reviews, Wang et al. [4]} observed seven intentions behind link sharing and their developer survey results suggested that link sharing is useful.
At the same time, Hirao et al. [5]} categorized five kinds of review linkage, such as patch dependency, broader context, and alternative solution.
To aid such practice, Wang et al. [6]} proposed a linkage detection using textual contents and file location.
